First of all, it's heavier than the old one and seems more solid when it closes. I think we need a better closer, though, because it seems to slam too hard. I will ask the installer if the closer can be adjusted. I love the built-in deadbolt lock. Now I feel more secure with both doors locked when I stay alone. Because of the quality of the product, if someone tried to break in I'm sure the noise would alert me long before they got in.....in time to get some help. Glass seems much thicker than old one, too so it would take a sledge hammer to break it! I would definitely recommend Larson full-view storm door.
